I saw a similar post someplace and decided to make my own. In no particular order and certainly with omissions, I present my list of things people assume I like but I don't.

In Music:

Metallica:
I love hard rock but I've never found this group the least bit interesting. I just don't get what people see in them. In the same time period Rage Against the Machine and Tool were far more interesting hard rock bands.

U2:
I love my Irish heritage but I can't find much to like about this band. People have been raving about them to me since they first appeared on the music scene but I've never found much to appreciate. To me it's all just unimaginative pop.

Kurt Cobain:
I liked Nirvana OK, but as time passes it certainly seems like Dave Grohl was the real the musical genius in that band and Pearl Jam had the better overall chops.

In TV and Movies:

Barbie Doll celebrities:
I really don't understand why people get so hot and bothered over women such as Jessica Simpson, Paris Hilton, Britney Spears and Lindsay Lohan. Certainly they are reasonably attractive but no more so than so many another women. It seems like there is some weird priesthood of fame that has anointed these women as their princesses without consulting the real world.

Indiana Jones:
I've found all the movies about that character mildly interesting romps barely worth the price of admission.

The Simpsons:
OK, I know I just pissed off all my friends, but as much as I liked Matt Groening's Hell comics I never understood the obsession with this cartoon. It's certainly funny but I've never felt the same level of obsession as most of my peers.

Seinfeld:
Being a life long Bostonian, I guess you could say I have a natural dislike for all things New York but for whatever the reason I just don't see what's so great about this show. I think it's OK and I've laughed at it at times but not anything like most people.

The Godfather movies:
Yeah some mobsters killed each other. Next.

In Books:

Stephen King novels:
I think I've only finished one of his novels but I've started many more. In my humble opinion they are all crap.

John Grisham novels:
Yawn.
